The risks of minimally invasive surgery for synovial cysts of the hip include two main risks: anesthesia and complications. Minimally invasive surgery for synovial cysts of the hip generally requires lumbar anesthesia, which may cause chronic back pain after anesthesia, and in some patients, anesthesia allergy or even shock may occur. Minimally invasive surgery for synovial cysts in the hip joint is usually performed by inserting an arthroscope to find the location of the lesion, and then using electrocoagulation or planer to remove the lesion; complications may occur during this process, such as damage to nerves and blood vessels in the joint, resulting in the risk of bleeding. In addition, after minimally invasive surgery for synovial cysts of the hip, bed rest is required for a long period of time, during which bed rest complications, such as bedsores and crural pneumonia (infection of the lungs due to the accumulation of respiratory secretions), may occur. Although minimally invasive surgery for synovial cysts of the hip joint carries certain risks, the doctor will conduct a comprehensive assessment for the patient before the surgery, and minimally invasive surgical treatment will be chosen only when the benefits generally outweigh the disadvantages. Patients should actively cooperate with the doctor’s treatment and strictly observe the precautions before and after the operation.
